Grade Control Evaluation Geologist

Purpose of Role

To evaluate and monitor the quality and quantity of mineral resources extracted, by conducting detailed geological assessments, to ensure mining activities are in line with production targets and geological models. To construct geological grade control models, dig plans and conduct short term reconciliation, ensuring regular mapping and structural interpretation for Block models and geological levels is done tooptimise resource extraction.

Grade Control

• Construct and maintain up-to-date Grade Control Models to enable the comparison of actual mining outcomes to geological models.
• Provide updated grade control wireframe and grade control model using all structural and mapping data, enabling an accurate determination of the grade, quality and distribution of mineral resources.
• Flag risk and/or opportunity areas after any grade control model update, adjusting models to improve accuracy.
• Work closely with short term and production engineers and metallurgist to optimise operating development and maximise ore extraction to optimum grades.
• Incorporate pit mapping, pit face sampling geology and pit geotechnical mapping into grade control models to provide a well-rounded view of the pit environment.
• Conduct periodic model reviews, audits and field investigations, QA/QC (Quality Assurance/Quality Control) to ensure models are an accurate representation of actual pit activities.
• Provide input into the construction of the Grade Control Dig Plan to align geology and mining activities.

• Implement and monitor quality assurance programs to ensure accurate records are maintained for face sampling, camera mapping, RC logging, assay results and all geological activities.
• Contribute to ongoing geological improvement by analysing existing processes and offering suggestions for enhancements.

• Manage the Grade Control Database to enable accurate grade control quality and quantity reconciliation per mining block.
• Monitor the input of data, ensuring accurate geological data capturing into the database.
• Provide updated geological and structural maps of all pit excavations to support efficient mining operations.
• Provide structural data for geotechnical support in bad ground areas in the pit, enabling the other drilling team to work around said areas.

• Responsible for mill-head grade, production, pit, and historical reconciliation to identify, analyse and report on variance between planned and actual results that highlights opportunities.
• Conduct dilution and ore loss reconciliation per block on a monthly basis and recommend improvement strategies.
• Reconcile volumes between grade control estimates, survey measure and actual count, to enable the implementation of modifications to sampling practice or to the methods or parameters used to calculate grade, tonnage or contained metal.
• Reconcile declared ore mined and grade control model, to enable the calculation of the monthly grade control estimation accuracy.
• Declare planned and scheduled feed grade total and per plant to provide a view of the performance of the mining plant operations.

• Keep statutory and internal reporting as required, ensuring all required periodic month end grades reporting is completed and distributed on time.

• Provide input into required changes in resources (financial or non-financial) to enable the achievement of team and/or own objectives.
• Determine resource needs of the team and/or own area of work to achieve business outcomes.
• Request and allocate required assets and/or resources for the fulfilment of work objectives to guarantee quality outputs.
• Monitor the use of assets and resources within the team and own area of responsibility, to ensure assets and resources are consistently and appropriately utilised and managed.
• Provide staff with day-to-day direction and tasks aligned with Departmental procedures, to enable the usage of less resources more efficiently.

• Identify potential geological risks that could impact mining operations and recommend mitigation strategies to ensure hazard management plans are observed.
